Product details
Overview
SF16GH from Taiwan Semiconductor is a 400V, 1A super fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 35ns reverse recovery time, 1.30V forward voltage at 1A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.
For engineers reviewing the SF16GH datasheet, SF16GH pinout, SF16GH application, or SF16GH equivalent, key selection criteria include its 400V repetitive peak reverse voltage, 30A surge rating, 150°C max junction temperature, low VF for reduced conduction loss, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This single-die silicon rectifier uses optimized epitaxial structure to achieve super-fast recovery (trr ≤ 35ns) while maintaining low forward voltage. Its 400V VRRM and 1A average forward current rating target mid-voltage DC-DC and SMPS secondary-side rectification.
Thermal performance is defined by RθJL = 20°C/W and RθJA = 80°C/W, enabling reliable operation up to 150°C junction temperature. The device exhibits 10pF junction capacitance at 1MHz/4V, supporting high-frequency switching efficiency.

| VF | 1.30 V @ 1A, 25°C - Forward voltage drop; determines conduction loss (1.3W at 1A) and thermal rise in rectifier path |
| IFSM | 30 A - Non-repetitive surge current rating; supports inrush and transient overload without failure |
| TJ(max) | 150 °C - Maximum junction temperature; allows operation in under-hood automotive environments with limited airflow |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R04 | 400V VRRM, 1A IF, 30ns trr, TO-220AC package (vs. DO-41); VF = 1.35V @ 1A | Higher thermal mass but requires PCB footprint change; better for >1A continuous or forced-air cooling | Select when higher surge robustness or heatsink mounting is required; not drop-in due to package mismatch |
| ON Semi MUR140 | 400V VRRM, 1A IF, 50ns trr, DO-41 package; VF = 1.25V @ 1A; no AEC-Q101 qualification | Slower recovery increases switching loss above 100 kHz; lacks automotive qualification | Acceptable for cost-sensitive industrial adapters where AEC-Q101 is not mandated |
Compared with STTH1R04 and MUR140, SF16GH uniquely combines DO-41 form factor, AEC-Q101 qualification, and 35ns trr-making it optimal for space-constrained, thermally demanding automotive and industrial SMPS where pin-compatible reliability is essential.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of SF16GH?
The SF16GH has a VRRM rating of 400 V, meaning it can reliably block up to 400 volts of reverse voltage in repetitive operation. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2104). Designers must ensure that peak reverse voltage in the application-including ringing and transients-stays below this limit to prevent breakdown. The SF16GH is part of the SF11G–SF18G series where "16" directly indicates the 400V rating.
Is SF16GH qualified for automotive applications?
Yes, SF16GH is AEC-Q101 qualified, as explicitly stated in the FEATURES section and Ordering Information notes of the Taiwan Semiconductor datasheet. The "H" suffix in SF16GH denotes AEC-Q101 qualification, covering stress tests including temperature cycling, humidity bias, and mechanical shock. This makes SF16GH suitable for under-hood and cabin automotive systems such as body control modules, infotainment power supplies, and ADAS sensor interfaces.
What is the forward voltage (VF) of SF16GH at rated current?
The SF16GH exhibits a typical forward voltage of 1.30 V at 1 A forward current and 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At higher temperatures (e.g., 125°C), VF decreases slightly (~1.15 V), which is typical for silicon diodes and beneficial for thermal stability in high-ambient environments.
What package type does SF16GH use, and what are its key mechanical properties?
SF16GH uses the DO-204AL (DO-41) axial-leaded package, with pure tin-plated leads compliant with J-STD-002 solderability standards. The molding compound meets UL 94V-0 flammability rating, and the device passes JESD201 Class 2 whisker testing. Polarity is marked by a cathode band, and the approximate weight is 0.350 g. This package supports both through-hole assembly and automated tape-and-reel handling (5,000 pcs/reel).
How does SF16GH compare to SF15GH and SF17GH in terms of electrical parameters?
SF16GH shares identical ratings with SF15GH and SF17GH for IF (1 A), IFSM (30 A), TJ(max) (150°C), and trr (≤35 ns), but differs in VRRM: SF15GH = 300 V, SF16GH = 400 V, SF17GH = 500 V. VF also scales slightly-SF15GH/SF16GH = 1.30 V, SF17GH = 1.70 V-due to higher voltage-rated die. All three are AEC-Q101 qualified and use DO-41 packaging, enabling direct substitution only when voltage margin and VF trade-offs are acceptable.
